annarcaron/ Specification of Letters Patent.

Application filed November 11, 1911. Serial No. esaseo To all whom it may concern Be it known that I, PIERRE nOv xrna- MONT, a subject of the King of Belgium, residing at Brussels, Belgium,have invented certain new and .useful Improvements in Lubricators, of which the following is a specification.

This invention relates to improvements in lubricators, its primary object being to provide a hi hly sensitive valve adapted to be 0 erated vibration of the apparatus to w 'ch the filbl'iCtltOl is attached, to ermit the lubricant to be fed or distribute to the machine.

The valve com rehended by my invention is freely mountetf'upon a seat and normally closes the distributing conduit in an air tight manner, when the machine is at rest, thus minimizin any waste of lubricant but assuring a sup Ty ofoil when the apparatus a in motion, t e amount of said supply bein proportionate to the amplitude of the vi ration imparted to said valve,

Other advantages of my device are that,

owing to the peculiar form of valve closure, I

the wear on said valve is negligible, and any impurities contained by t e oil are prevented from collecting in the, discharge opening through which they are permitted to pass, or are forced, by the oscillating movement of the valve, which will thus not be interfered with in operation.

Still a further object is suhserved bythe use of novel means for regulatingthe am-. plitude of vibration of my valve so that in cold weather, for instance, when the oil'is heavy, the supply thereof may be suitably controlled.

The valve rests on a seat formed by the cd e of the discharge 0 ening, and" is in sta le equilibrium on the atter. The vibrations ofthe machine to which the lubricator is applied to, cause the valve vto oscillate, and it swings about aoint .of rest on the edge of the opening a oresaid, thelateral movements of the upper portion of the valve raising it from its seat and permitting the oil to escape into thedischarge passage.-

For a full understanding of the present invention, reference isto be had to the following description and the accompanying drawings, in which- Figure 1 is a vertical sectional view of a lubricator constructed in accordance with my invention; and Fig. 2 is an elevation thereof.

tion and on the several figures of the drawin s, similar parts are referred to by like re erence characters.

Specifically describing my invention, and

referring to the drawing, A designates the valve proper which is contained within the body of the lubricator B, the latter being provided with a closure, orcap C, therefor. The valve A is conical in shape and formed with a convex base, in the center of which is located a projection or obturating point 2.

Extending upwardly upon which is screwed an adjusting nut .4. 'A set-screw 5 extends through a lateralopening in the nut 4, by means of which said nut may. be positively adjustment on the spindle 3.

As will .be clearly noted in Fig.1 of the from the upper por-v tion ofThe valve 1 1s a threaded spindle 3,

held atits proper; I

drawing, the cap 0 is conically recessed to 4 permit the upper-end of the valve rod 3 with the nut 4 thereon, to be received there into. Said cap 'by its threaded connection with the bod of the lubricator may be suit ably adjuste with respect to-the nut 4, and in'this manner regulating the amplitude of the oscillation of the valve, as will be here inafter more fully described. A collar 15 'is secured to the cap. C in order to lock the same in position after it has been adjusted.

' The convexbase of the'valve 1 is seated on the. oppositely convex bottom 8 of the bod B, said bottom being provided cen tral y thereof with the distributing passage. 6 extending .theret-hrough. The upper por tion of the passage 6, adjacent its opening into the compartment 7 of the'body, is enlarged to formanjannular'chamber or recess' 9, for the v urpose of facilitating the movements of t e point 2 extending into the pasage, as well as the escapin of the oil. The up r diameter of the con nit 6 is practically t e same as that of the base of the point 2;

q The body B is lprovided adjacent its lower urality of openings 10, af-= rtion with a p ording passage to the oil into the compartment 7.

As will be. apparent from the fore oingdescription, the center of avity o the valve A, while referably a ove the point easily shifted as; required Q a otness ment on the edge of" the outlet passage 6 which permits oil to be fed methodically and continuously from the compartment 7, dur' the operation of the machine to which it is attached. The supply of the oil may be regulated at will by ad uStment of the nut 4 with respect to the cap 0, or vice versa, according to the requirements and the amplitude of theoscillations of the valve, as Well as its sensitiveness. Accordingly as the nut 4 is shifted upward or downward on the screw threaded rod 3, the clearance between the cap C and the nut 4, and consequently the amplitude of oscillation of the valve A, isreduced or increased; It will be readily understood that the operation will result in increasin or reducing the space uncovered between t e point 2 and the edge 12. When, therefore, it is necessary to have a larger supply of oil for instance in cold weather.

when the oil is thicker, it will be only necesgrip to lower the nut 4. The nut 4 may also I The regul a. valve rod, said valve norma 1y closing the distributing conduit aforesaid and. resting in stable equilibrium thereon, andv an adjustable weight mounted on the valve rod aforesaid.
